Detailed explanation-1: -Haploid cells are represented as “n” in terms of ploidy, diploid cells are represented as “2n”. In humans, 2n=46. In humans, all the somatic cells of the body are haploid cells; it contains half the chromosomes contained in the normal diploid cells.

Detailed explanation-2: -The number of chromosomes in a single set is represented as n, which is also called the haploid number. In humans, n = 23. Gametes contain half the chromosomes contained in normal diploid cells of the body, which are also known as somatic cells.

Detailed explanation-3: -A haploid cell contains a single set of chromosomes (n), whereas a diploid cell contains two sets (2n). In humans and most other multicellular organisms, the majority of cells are diploid, and only the gametes (egg and sperm cells) are haploid.

Detailed explanation-4: -During meiosis, the ploidy is reduced from diploid (2n) to haploid (1n) in production of eggs and sperm. With the successful union of egg and sperm, the normal diploid (2n) complement of chromosomes is restored.

Detailed explanation-5: -Which Cells are Haploid? Gametes or germ cells are haploid cells (example: sperm and ova) containing only one set (or n) number of chromosomes and autosomal or somatic cells are diploid cells containing 2n number of chromosomes. The number of chromosomes (n) differs in different organisms.
